When you’re applying vacuum to an application in your lab, it can be easy to forget what’s going on behind the scenes. With a central vacuum system, every vacuum line serving your lab sucks gases, vapors and maybe even bio-aerosols into a common conduit. Once there, they mix with the emissions from other vacuum applications. As long as they stay in the vacuum lines, they will cause you few problems – but what happens when you’re operating an application and someone opens a valve somewhere else?
“VACUU·LAN® local vacuum networks protect your science.”
Vapors rush into the newly opened valve, increasing the pressure within the vacuum lines. Suddenly, your operation under vacuum has become the low-pressure point. The introduced vapors or gases may then move straight to your application, contaminating your sample or causing a pressure spike that may violate a critical parameter.
VACUU·LAN® local vacuum networks protect your science in two ways. By producing and controlling the vacuum in each lab individually, there is no risk of cross-contamination from another lab. And by equipping each vacuum turret with its own check valve to control flow in the network, work at one turret is much less likely to cause pressure spikes or cross-contamination at another turret on the same network.
To see this technology in action, watch the video below, where we use a smoke test to show how a VACUU·LAN® network protects against pressure interference and cross-contamination.
